Application filed February 13, 1909. Serial No. 477,651.

To all whom it may; concern:

Be it known that I, \VlLLiAM A. TUR- narnn, a citizen of the United States, and a resident of Lancaster, in ,the county of Erie, State of New York, have invented certain new and useful Improvements in Electrical Systems of Distribution, of which the following is a specification.

My invention relates to electrical systems of distribution and apparatus therefor and my improvements are more especially designed to render such systems-more economical and etticieut in operation and construction."

More particularly my iugprovements are especially applicable to systems in which a consumption circuit and 115 load and 111 which a storage battery and booster are operatively arranged to maintain the load on the main source of electrical energy substantially constant.

One object of my invention is to provide an arrangement or apparatus which is especially economical and etlicient and a booster which is provided with field and armature windings so arranged that part of these windings eoact tod'rive the booster and partcoact to provide the booster voltage for the purpose of controlling the fiitteryaction.

Further objects, advantages and features will more clearly appear from the detailed description given below taken in connection with the accompanying drawing which diagrammatically shows a system and arrangement embodying one form of my invention.

Referring to the drawing, 1 represents a .main generator with compound field windings. The-main generator 1 forms a source of electrical energy feeding and supplying wthe#consmnption circuit 2, 2, and its load 1 represents a storage battery connected across the mains 2, 2, by a circuit 5, In

series in the circuit 5), 5, is a booster (3 arranged to produce the proper electromotive force in the circuit 5, 5, to causethe battery .to charge or dlscharge,nraccordance Wlth the electrical condition of the system.

The booster 6 is provided with two armature windings on the same core structure,

which armature windings may be represented by the full line circle ,7 and the dotted-line circle 8.. Theavindirigsrepresented -mains or consumption circuit '2,

battery circuit 5 by means of brushes 9, 9.

10 represents a field coil for the booster which produces a magnetomotive force in the proper direction to produce a flux component which results in an electromotix e force being produced at. the brushes 9, 9. The-field coil 10 is connected in series with a counter electromotive force machine 11in a circuit 12, 12, 12 connected across counter machine 11 is provided with a field coil-13 inshunt to a small resistance 14in series in the consumption circuit 2.

Theparts so structed and arranged that when there is a predetermined normal load upon the, consumption circuit the current in field coilg13 causes an electromotive force to be produced in the counter machine or exciter, 11 just by 7 are connected in series in the boosterthe The Patented Nov. 23,1909.

far described areiso con 1 equal to and opposite in direction tothe electromotive force applied by the mains 2, 2. Under these conditions,- thereforefno current will flow in the field coil 10, and although the booster is being rotated no electromotive force will be, produced at thebrushes 9, 9, and the battery 4 is allowed to float across the line. When, however, an increased load occurs upon the consumption circuit the field strength of coil 13 is thereby increased, which increases the-electromotive force of the counter-machine 11, so that-a current is forced through the field coil 10 to excite. the same and produce an electronictive force in the booster at the brushes 9, 9

in a direction to cause the battery 4 to discharge and take substantially the increased load.. 'hen the load on the system falls below the predetermined normal Value the counterelectromotive force of the machine ll is decreased, thereby allowing current to flow in the field windings 10 in the opposite direction, so that an electromotive force is produced at the brushes 9, 9 in the opposite direction to cause the battery to be charged fromthe main or consumption circuit 2, 2.

In order to drive the booster and to provide means for this purpose without the use of an additional dynammelectric machine I provide the armature windings ,8 and brushes 15, 15, therefor, The minare widtlings represented by. 8 are connected in h the" circuit 16, 16, across the line and are arranged to act as motor windings. The flux component for coacting with these windings 8 to produce the motor action is furnished by windings 17 connected across the mains tional resistance 21 included in series with the motor brushes 1?) vt'or bringing the machine up to speed. This variable resistance 21 is controlled by a knife switch 22 having but tlnregulation ljtl'ie'arrangement is except ionally eliirient.

Although I have described my invention In order that the flux components prowith respect to a particular system it will duced by the field fluxes 17 and 10 may be be evident that my improvements are equally 1 separate and controllable independently of .well adapted to many other systems and areach other these field coils are displaced rangements'.
